Java Servlet代理

Question

如果我将系统设置为在servlet的doPost方法中使用代理，那么方法中的所有连接都将通过代理吗？例如：

    protected void doPost(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {

System.setProperty("http.proxyHost", "myProxyServer.com");
System.setProperty("http.proxyPort", "80");
